[0045] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0046] In traditional storage systems, ESMs (Expansion SAS Modules) and hard drives are typically configured in a modular design, where the ESM module is responsible for expanding the input SAS signal to multiple hard drives to increase storage capacity. However, this modular design often requires a fixed space to install the ESM modules and hard drive trays. Due to the physical size of the ESM modules and hard drive trays and the space required between them, traditional storage systems have limitations in space utilization within the chassis, making it difficult to achieve high-density storage, which in turn affects overall storage capacity. High-density storage requirements mean that more hard drives and ESM modules need to be installed in a limited space, which can lead to heat dissipation issues as traditionally designed heat dissipation systems may not be able to effectively handle higher heat loads. Maintenance of hard drives and ESM modules also becomes more difficult, and seamless expansion is not supported. When more hard drives or ESM modules need to be added, the entire chassis may need to be replaced or additional external equipment may be used, which increases cost and complexity.
[0047] The following embodiments of the present application provide a hard disk storage expansion system for achieving high-density storage of hard disk space.
[0048] The principles and implementation methods of a hard disk storage expansion system of this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the hard disk storage expansion system of this embodiment without creative work.
[0049] like Figure 1As shown, this embodiment provides a hard disk storage expansion system. The hard disk storage expansion system 1 includes: a chassis 11, a hard disk tray 12, a hard disk 13, a signal expansion module 14, and a data center security control module 15. The hard disk tray 12 is arranged inside the chassis 11 and is used to manage multiple hard disk groups. The signal expansion module 14 is connected to the hard disk tray 12, and the signal expansion module 14 is arranged below the hard disk tray 11. The hard disk 13 is hot-swappable and maintained through the upper side of the chassis 11. The data center security control module 15 is connected to the signal expansion module 14, and the signal expansion module 14 is hot-swappable and maintained through the front side of the chassis 11.
[0050] Exemplarily, the signal expansion module 14 is an ESM (Expansion SAS Module), which is an expansion module of SAS signal. The SAS signal of input can be expanded to the hard disk connected to allow the storage system to connect more hard disks, thereby increasing the storage capacity of the storage system. The ESM module can receive the X16 signal from the host controller or other SAS devices and expand it to the hard disk on the hard disk tray. The inside of the ESM module includes multiple SAS ports, each of which can be connected to one or more SAS hard disks. The SAS signal of input is distributed to each port by the internal circuit of the ESM module, thereby realizing the expansion of the SAS signal.
[0051] The Data Center-Ready Secure Control Module (DC-SCM) 15 manages information across the entire system. It manages system security and status monitoring, including security management, such as access control, identity authentication, and data encryption, and status monitoring, such as monitoring hard drive status, network status, and hard drive failures. The DC-SCM is connected to the signal expansion module, communicating with the hard drives through the module to manage and monitor their status and configuration.
[0052] The chassis 11 is a 4OU chassis, wherein 1OU=48mm, and the maximum height of 4OU is 192mm.
[0053] The hard disk 13 is a 3.5" HDD storage medium. The hard disk is 3.5 inches and has a size of 146.99mm x 101.85mm x 26.11mm in length x width x height.
[0054] According to the above description, the hard disk storage expansion system provided by the present application can combine the hard disk group and the signal expansion module in a top-down architecture, thereby increasing the number of hard disks supported by the hard disk storage expansion system and achieving high-density storage in the storage system. At the same time, the hard disks can be hot-swapped and maintained from the top side of the chassis, and the signal expansion module can be hot-swapped and maintained from the front side of the chassis, which increases the spacing between the hard disks and improves the heat dissipation capacity of the storage system. The hard disk storage expansion system of the present application not only optimizes the internal space of the chassis but also facilitates the maintenance operations of the hard disks and signal expansion modules in the storage system, thereby improving maintenance efficiency and chassis utilization.
[0055] Figure 2-4 Figure 2 is a schematic diagram of a traditional storage system. The traditional storage system 2 includes a chassis 21, hard drive trays 22, hard drives (HDDs) 23, a signal expansion module (ESM) 24, and a data center security control module (DC-SCM) 25. As can be seen, in this traditional storage system, the DC-SCM 25 is located at the front of the chassis 21, while the signal expansion module (ESM) 24 is located in the middle of the hard drive array within the chassis 21. This prevents expansion of the number of hard drives, limiting the space available for 105 hard drives.
[0056] See also Figure 5 and Figure 6 In one embodiment of the present application, the data center security control module 15 is inserted into the signal expansion module 14, and the data center security control module 15 is hot-swappable and maintainable through the front side of the chassis 11. The data center security control module 15 is located on the left side of the front of the chassis 11, and the signal expansion module 14 is located on the right side of the front of the chassis 11.
[0057] Exemplarily, the signal expansion module 14 comprises two parts. The area of the first part of the signal expansion module 14 is larger than that of the second part. The data center security control module 15 is located in the first part of the signal expansion module 14. The area of the data center security control module 15 is less than one-third of the area of the signal expansion module 14 and is located at the lower left side of the signal expansion module 14. The data center security control module 15 comprises a first side 151, a second side 152, a third side 153, and a fourth side 154. The first side 151 of the data center security control module 15 is disposed in front of the signal expansion module 14. The first side 151 of the data center security control module 15 and the front of the signal expansion module are located in the front of the chassis 11. The data center security control module 15 and the signal expansion module 14 can be hot-swapped and maintained from the front of the chassis.
[0058] By integrating the Data Center Security Control Module (DC-SCM) into the first section of the Signal Expansion Module (ESM), the internal chassis space is optimized. Integrating the DC-SCM and the Signal Expansion Module reduces the space occupied within the chassis. Furthermore, placing the DC-SCM within the first section of the Signal Expansion Module fully utilizes the ESM's space, avoiding waste. This integration allows for hot-swappable maintenance from the front of the chassis without opening the chassis, improving maintenance efficiency. Furthermore, placing the DC-SCM within the Signal Expansion Module reduces the number of internal wiring and lowers system costs.
[0059] See also Figure 7 In one embodiment of the present application, the data center security control module 15 is a square chip. The first side 151 of the square chip is located on the front side of the chassis 11. The second side 152, third side 153, and fourth side 154 of the square chip have multiple grooves for insertion into the signal expansion module 14. The third side 153 of the square chip has more slots than the second side 152 and fourth side 154. The square chip is inserted into the interior of the signal expansion center 14 with the third side 153 as the inner side.
[0060] The data center security control module is secured to the signal expansion module via slots. By positioning the third side of the square chip, which has multiple slots, as the inner side, it can bear the primary weight and pressure of the data center security control module. The slots on the third side enhance the stability of the connection between the data center security control module and the signal expansion module, preventing them from falling or shifting. Furthermore, since the third side of the data center security control module is closer to the interior of the chassis and more prone to heat accumulation, designing more slots on the third side increases the contact area between the data center security control module and the signal expansion module, facilitating heat dissipation and improving the chassis's heat dissipation performance.
[0061] In one embodiment of the present application, the signal expansion module 14 is connected to the multiple hard disks 13 to expand the input signal to the multiple hard disks; the data center security control module is used to store system information for management.
[0062] For example, the signal expansion module 14 has snaps on its two rear sides, which can be plugged into the hard disk tray 12. The hard disk tray 12 has multiple hard disks 13 installed on it. The signal expansion module 14 can expand the received input signal to the hard disks 13 on the hard disk tray 12. The SAS signal expansion module can expand the input X16 SAS signal to the SAS signal of 112 hard disks.
[0063] Compared to the traditional method of embedding the signal expansion module in the middle of the hard drive array, this signal expansion module and the hard drive tray are arranged one above the other, allowing each row of hard drives to add space for an additional hard drive, increasing the scalability of the storage system. Furthermore, the added space can be distributed between each hard drive, increasing the heat dissipation path between the hard drives, helping to optimize air flow within the chassis, thereby improving heat dissipation efficiency and extending the life of the hard drives and other components.
[0064] See also Figure 8 In one embodiment of the present application, the hard disk storage expansion system further includes a handle 16 disposed on the front side of the chassis 11 for pulling the hard disk tray 12 and the signal expansion module 14 out of the chassis 11. The handle 16, combined with the hard disk tray 12, enhances the overall strength and structural stability of the tray, ensuring durability even under frequent operation.
[0065] In one embodiment of the present application, the hard disk is inserted into the hard disk tray from the upper side of the chassis. The chassis 11 includes 7 rows of hard disk groups, each row of hard disk groups includes 16 hard disks, and can accommodate a total of 112 hard disks.
[0066] Please continue reading Figure 8 In one embodiment of the present application, the hard disk storage expansion system further includes a plurality of fan modules 17, the fan modules 17 are located behind the hard disk tray 12, and the fan modules 17 are arranged on the rear side of the chassis 11 for dissipating heat from the chassis.
[0067] Depend on Figure 2-4It can be seen that the chassis of the traditional storage system 2 is provided with 7 rows of hard disks 23, with 15 hard disks in each row, for a total of 105 HDD hard disks 23. The HDD hard disks 23 and the ESM module 24 are both installed and maintained on the chassis 21, and when maintaining the hard disks and ESM modules, the entire tray needs to be pulled out for maintenance. Compared with the method of arranging the ESM module in the middle of the hard disk group in the traditional storage system 2, the ESM module 14 and the hard disk tray 12 are structured up and down in this application, and the ESM module 14 is arranged below the hard disk tray 12, freeing up a certain amount of space in the 7 rows of hard disks 13 inside the chassis 11, so that each row of chassis can accommodate one more hard disk, that is, each row has 16 hard disks, for a total of 112 HDD hard disks. The HDD hard disks 13 are installed and maintained from above the chassis 11. The ESM module 14 is connected to the hard disk tray 12, and the data center security control module 15 is set inside the ESM module 14. The data center security control module 15 and the ESM module 14 can be walked in front of the chassis 11 for hot-swappable maintenance. Since the width of the chassis currently on the market is 536mm, the width of the ESM is 46mm, and the width of a hard disk is 26.11mm. Compared with traditional storage solutions, the hard disk storage system 1 of the present application adds one hard disk while removing the ESM module in each row, that is, 46-26.11=19.89mm, which will have an extra 19.89mm of space, which can be distributed to the distance between each hard disk. The extra distance can increase the heat dissipation channel between the hard disks, thereby accelerating the heat dissipation efficiency.
[0068] In summary, the hard disk storage system in this application supports 112 hard disks by optimizing the upper and lower spaces of the signal expansion module and the hard disk tray, and inserting the data center security control module into the interior of the signal expansion module, thereby achieving high-density storage in the current 4OU storage device. Placing the signal expansion module under the hard disk tray increases the distance between the upper hard disks, which helps to dissipate heat in the storage system. At the same time, the signal expansion module can be maintained in front of the chassis, and there is no need to open the chassis for maintenance, which improves maintenance efficiency.
